Science has advanced to a very large extent. All the science that exists today wasn’t the result of a single day but it has evolved over years. Science has travelled or progressed from macro to micro and finally to nano scale development. In that context, nanotechnology is a newer science. This technology has been widespread ever since its advent.

How do nano lubricants affect mechanics of devices?

Lubrication is one of the fields which use nanotechnology. As the science advanced, we got to know different machinery. Same as science, the machines also went from macro to micro and then to nano. The path was obviously not an easy one. As the machines became smaller, we encountered the problem of lubrication of their parts. Lubrication is must for longevity of the device but it became a barrier as the scales of machinery became smaller.

Since ages lubrication has evolved as a science that involves physics, chemistry, contact mechanics and fluid mechanics. Nano lubrication is the science that controls adhesion, friction and wear of the surfaces that come in contact at nano scale. Nano sized lubricants are the agents which check all this.

Our understanding of lubrication from its traditional use is that lubrication is necessary to prevent wear and tear of the surface and also that some fluid pressure should be maintained to avoid the two surfaces from coming in contact. The fluids used provide hydrostatic and hydrodynamic pressures to support the load.

What are the important properties of lubricants of nano size?

For lubrication of two surfaces at nano scale, we require a long lasting surface film that may consist of one or two layers of particles.

Also ability of the film to withstand constant rubbing or repeated contact is important. To accomplish this one should keep in mind that the molecules of the film should not be non-degraded as the degradation may spoil parts of the device.

The film produced to serve the purpose of a nano lubricant should be self repairing. This means that if the particles from one part are removed by oxidation, evaporation or by contacts, the particles from other locations can move in and fill the space.

Temperature stability of nano lubricants is a must as the device may get heated up by constant rubbing.

Some other desirable factors are resistance to oxidation and decomposition.

It should be non-volatile to be effective.

The particles of this film should provide good adhesion and cohesion.

For example: Perfloropolyether or PFPE is one of the nano lubricants that is used in Magnetic head-disk lubrication. It is highly resistant to oxidation. It is non-volatile. It forms hydrogen bonding and provides good adhesion forces. It withstands high centrifugal forces that arise from disk rotation.

In modern day science we define nano lubrication as a means to obtaining control of friction, adhesion and wear and tear where the effect is controlled by the nano lubricants at the nano scale. Hence, use of these is very important for large firms dealing in mechanical part manufacture.

Punjabis are known to be a fun loving and loud community. Their weddings are grand and filled illustrated ceremonies, colorful clothing and loud music. Punjabi weddings are an extension of the Punjabi culture and their strong traditional rituals are reflected during it.

A typical Punjabi wedding is grand, whether it is the food, the numbers of guest the clothes or the music it everything has to be large and alluring. Normally a Punjabi wedding has several functions which last for about 3-4 days, with different ceremonies happening every day.

The wedding invitation for such a grand wedding is also needed to be equally grand. Like the wedding, the Punjabi Wedding Card is also quite colorful and elaborate. It effectively depicts the Punjabi culture and their generosity.

Impress Your Guest With Punjabi Wedding Cards

Usually theses cards are made in various colors and decorated with intricate designs. The design are all detailed and elaborate to make sure that the card stand out and creates a good impression among the guest. These invitations stand out from all the other Indian Wedding Invitations as they are one of the most bright and colorful cards.

Since the Punjabis are a traditional community, many of them prefer to print their Punjabi Wedding Invitations in the Punjabi language, to give it a more ethnic feel and please the traditional people.

One unique feature of the Punjabi Wedding Card is the designs of the card or on the cover. These cards are uniquely designed and have a splendor ethnic vibe decorated with loud colors such as green, red or blue decorated with golden or silver emblazed design.
